Funny how this otherwise great thread on Lionel Dealer Layouts keeps getting "bumped" with the copyright issue discussion.
It's all moot anyway. Or maybe I should say that Carp's book isn't the only source so no worries. See my post up above from several months back. I bought the fantastic DVD that offers all of the Lionel Dealer Display layouts including track plans, wiring diagrams, and a list of track and accessories needed. I'm building one now and the original plans have been invaluable.
Btw -- if I can assist anyone who wants plans, shoot me an email with the layout # and I'll provide them in pdf format.
